UC-MSC chondrogenic differentiation in pellet culture. A representative image of safranin o staining of UC-MSCs in pellet culture (a and b). Stronger safranin o staining is observed in UC-MSC pellets cultured at low oxygen tension (a) when compared to normoxic conditions (b). Higher PG/DNA ratio in pellets cultured at low oxygen tension is shown in (c) (median value and standard deviation: 0.05166 ± 0.02240; 0.07468 ± 0.01687 for and normoxia and low oxygen tension, resp.). p value < 0.05. Magnification 20x. Scale bar: 200 μm. n of samples = 3.
